1-1/4 inch PVC Schedule 40 Pressure Adapter Plastic x Male

1-1/4 inch PVC Male Adapter – Threaded Transition for Pressure and Drainage Applications

The 1-1/4 inch PVC Male Adapter is designed to connect a solvent-welded female hub to a threaded metal or plastic fitting. This component is used for joining PVC piping systems to threaded connections, typically in cold water distribution or non-pressurized DWV systems. Manufactured from Schedule 40 PVC, this fitting offers durability, chemical resistance, and ease of installation in code-compliant plumbing assemblies.

Application and Benefits

• ✅ Threaded MIPT End – Provides a secure connection point to threaded brass, galvanized, or PVC fittings.
• ✅ Solvent Weld Socket – Allows fast and permanent bonding to standard Schedule 40 PVC pipe using primer and cement.
• ✅ Corrosion-Resistant – Non-metallic construction is unaffected by rust or electrolytic degradation, suitable for aggressive water conditions.
• ✅ Suitable for Residential and Commercial Use – Used in potable water supply, irrigation, and drainage system transitions.

Specifications

• Material: Schedule 40 PVC (polyvinyl chloride)
• Nominal Size: 1-1/4 inch
• Connection: Socket x Male Iron Pipe Thread (MIPT)
• Pressure Rating: Up to 150 PSI @ 73°F (varies by system type)
• Compliance: Meets ASTM D2466, NSF 14/61 for potable water use

Installation Notes

Installation requires standard PVC solvent cement for socket end bonding. For threaded joints, use PTFE thread sealant or approved thread tape to prevent leakage. Avoid overtightening to maintain fitting integrity. Verify system pressure limits and installation requirements according to applicable codes (IPC, UPC, or local standards).

Common Use Cases

Frequently utilized in cold water lines, irrigation systems, and DWV transitions where a solvent-welded joint must interface with threaded valves or fittings. Also applicable in system repairs and lateral service lines where thread-to-glue transitions are required.

Technical Considerations

PVC male adapters must be installed with support to prevent mechanical stress at the threaded connection, especially in systems subject to vibration or temperature fluctuation. Avoid use in compressed air or gas systems. Always refer to local code for allowable materials and installation guidelines.

Choose the 1-1/4 inch PVC Male Adapter when specifying fittings for threaded transitions in pressure or drainage systems. Engineered to meet performance standards in a variety of environments, this fitting is a dependable solution for durable, corrosion-resistant connections.
